Anemias do not all stem from the same causes.
Malnutrition or malabsorption of nutrients can contribute to vitamin deficiency anemia and iron deficiency anemias.
Acquired anemias affect about 4 million individuals in the United States, and over 50 percent of these are under age 45, although less than 10 percent of cases occur in children and adolescents.
The child's medical history will be taken, including the child's age, symptoms, illnesses, and general state of health, and a family history of ancestry and known inherited anemias will be noted.
In some anemias, a bone marrow sample will be removed (bone marrow biopsy) for microscopic examination, especially to confirm iron deficiency anemia or the megaloblastic anemias.
